GEORGE M. ANDEnsoN, or WASHINGTON,

SHREDDED WHEA COMPANY,

made a certain new and useful Invention in Machines for Manufacturing Filamentous Biscuit; and I declare the following to be a full, clear, and exact description of the I same, such as will enable-others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of-reference marked thereon, which form a part of this specification.

Fig. 7 is a detail plan view of the same. Fig. 8 is-a detail side view of a section of the lower belt. I c Fig. 9 is a detail plan view of the same. The invention has relation to machines for manufacturing filamentous biscuit, wherein a 'continuousband of filaments is laid down from the shredding or reducing machines upon a moving carrier or belt, said band :being .usually transversely indented or out in straight lines, the object of the present invention being the economical production of a round or rounded biscuit. In carrying out this object means are r0 vided transversely dividing the ban of filaments on curved or crooked lines, approximately triangular parts of the band of. filamentous material being thereby cut away a between the biscuit, means being provided to convey these cut-away portions of the,fila inentous band to the hoppers ofgthe shredding machines, to be again used or shredded with other grain fed to said hoppers.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, theletter 1A designates the frame of a machine for cutting the endless band of filaments into uniform sections,

said machine shown and described generally in Letters Patent No. 681,656, dated August Specification of Letters Patent.

.27, .1901, and the present invention including certain modifications of this patented machine, as hereinafter explained. The frame A is provided with overlying tracks, 6, c and cl, upon which the endless upper, middle and lower chain belts, E, F and G, respectively travel, said belts passing over end sprocket wheels H, I and J.

The middle belt F constitutes an endless sectional an, havingbetween the sections or links t ereof narrow intervals for passage of the upper and lower cutter blades 15 and 21. The cutter blades 21 of the lower belt pass upwardly in succession between the sections of the middle belt, entering sufliciently therebetween to lift the filatrally of the paths 3 and-carrying end rollers 7, traveling upon the tracksc. Each pan 3 is substantially circular and is provided with short lateral upwardly extending flanges 8.. r

The links 9 of the upper belt E each carry, rigidly connected therewith, a depending cover plate 10, overlying and of similar form to that of the pan 3 corresponding thereto, said cover plate having downturned lateral flanges 11, of similar dimensions'to and cooperating with the flanges 8 as hereinafter stated. Each link 9 is provided with a reduced extension 12, engaging at one end "with a central seat 13 of the adjacent link, the links being pivoted together by transverse pins 1 1, located centrally of the cover plates andhaving end rollers 15, traveling upon the tracks a The arcuate knives 15 of the upper belt The 19 of the lower cutter belt G are pivoted together by transverse pins 19',

, carrying rollers 20, traveling upon the tracks lower knives d, and each link carries a pair of arcuate knives 21, cooperating with the-kmves15 of the upper belt in cutting the biscuit.

The cover plates 10 of the upper belt E are preferably rounded or beveled at the margins, to gather the filamentous material somewhat and give it shape as it presses thereon in its downward movement. At the adjacent edges of the sections this marginal bevel of the cover plates serves to compress the filamentous material against the rising blades of the lower knives 21, in this manner facilitating the action of the knives of the upper belt in'their descent, the upper and having a shearing action.

The n per and lower cutter blades or knives Wlll, in the cutting operation, inclose each biscuit, except at the portions of the sides bounded by the flanges 8 aiid 11, these flanges inclosing such portions of the biscuit,

r which is in this way entirely inclosed and guarded against the blast hereinafter described. In order to efiect the reciprocation of the I cutter blades of the upper belt, inclined or rate of speed, and are accurately formed and geared, 1n order that the action of the upper and lower knives shall be neat and close.

The filamentous material laid down upon the middle belt F by the reducing machines will fill the pan sections of the .belt and will bridge the narrow tapering spaces 3' between the an sections.

The tree s c and d, whereon travel the rollers of the middle and lower belts, as also the links of these belts, are of a breadth considerably less than the width of the ans 3 andof the filamentous band from WhlCh the biscuit are cut, so that the triangular pieces cut from said band in the making of the rounded biscuit will have their descent or fall facilitated, Transverse inclined bridge blocks 22 are located between the knives 21 of the lower belt G, and are-of a breadth (or length transverselfy) somewhat in excess of the breadth o the tracks 0 and d and the links of the belts traveling thereupon, whereby the filamentous material deposited between the pans 3 of the middle It and cut from between the rounded biscuit. will in falling be directed outwardly and enabled to drop freely. In the rise of the lower knives 2l,- the bridge blocks 22 between said knives engage lower notches 22 of the reduced extensions 4 of the middle belt, said notches having rounded lower corners. In this way the lower knives are accurately guided in making the-cut. The reduced extensions 4 of the links 2 of the middle belt F 'fit within central upper notches 21 of the knives 21 of the lower and the breadth of the track I) and of the links of the belt traveling thereon being less than the width of the pans 3, the branches of the blast chamber overlie the lateral margins of the .biscuit and ofthe filamentous band. The blast chamber 26 is suitably closed in at the ends.

Located below the blast chamber 26 is a. chute 30, also suitably closed in at the sides and ends, and through which the blast of the fan will carry thetriangular pieces of the filamentous band out from between the rounded biscuit, as also all loose filaments or scrap material located upon the belts and outside the lines of the inclosed biscuit, and, being assisted by gravity, will convey these pieces and material to an elevator 31, whereon they will be deposited and carried upwardly, being delivered from said elevator to the hoppers 32 of the reducing machines 33. v
